How does Naruto draw Namikaze Minato?

Print out what you want to draw, then draw a tic-tac-toe grid on the printed four generations of Huo Ying, and then put it on the paper you draw with a pencil, so that the tic-tac-toe of your four generations of Huo Ying is the same as that on the drawing paper, and then copy it on the paper according to the position of the characters in the original picture. You can also cover the original picture with a newspaper for extension painting. Pay attention to the outside line of the character, as long as the inside edge line is accurate, it will be almost the same.
